SPECIFICATION forming part of Letters Patent N o. 684,02 5, dated October 8, 1901.

Application led September l5, 1900. Serial No. 30,189. (No model.)

To @ZZ whom t may concern.'

Beit known thatI, HENRY STEPHEN WOOD, a subject of the Queen of Great Britain, residing at No. 100 Franklin street, North Melbourne, in the Colony of Victoria, have invented certain new anduseful Improvements in Acetylene-Gas Lamps, of which the following is a specification.

The object of this invention is to provide a means whereby acetylene gas may be burned in carriage or vehicle lamps in lieu of candles and by which the ordinary vehicle candlelamp can be converted into an acetylene-gas lamp with but slight alteration and with small expenditure.

In order to make my invention clear, I will refer in the following description to the accompanying sheet of drawings, in which Figure 1 shows a side view of a lamp provided with the apparatus for burning acetylene gas. Fig. 2 shows the apparatus in vertical section applied to a lamp, the lower portion of the lamp being shownin section. Fig. 3 shows a horizontal section of the apparatus, taken at line A A of Fig. 2. Fig. 4 shows a similar section taken at line B B of Fig. 2. Fig. 5 shows a vertical section taken on line C C of Fig. 2.

In the drawings, 1 represents the body of an ordinary lamp, and 2 a cylinder, which is closed at its bottom by a cap 3, screwing onto the cylinder. This cylinder has a screw-ring 4 encircling and secured to it. The top end of the cylinder 2 enters a cylindrical hood 5, the bottom end 6 ofrwhich screws onto the ring 4. This cylindrical hood rises above the top of the cylinder 2, and at its top any ordinary acetylene-gas burner 7 is set. The cap 3 has a rod 8 screwed into it and which projects upwardly within the cylinder 2 and has at its top a wedge-shaped head 9. A strip of iine wire-gauze 31 is set across the cylinder 2, near or at its top. A pipe 10 enters the cylinder 2 and rises Within it, terminating in a swanneck 11,and the end of which is arranged to lie directly over the wedge head 9 aforesaid. The pipe 10 is connected by a coupling to the pipe 12 and by means of which the latter may be removed when placing the lamp in position. The construction of the part is as follows: The end of the pipe 10 is set in a screw-boss `13, affixed to the cylinder 2. The end of the pipe 12 terminates ina disk 14. A washer 15 is set between theA boss and disk, and a cap 16 screws onto the boss 13 t0 hold the parts together. The pipe 12 is connected topipe 17 by flexiblehosing 18, or the parts 12 17 18 may be formed of a continuous length of iiexible piping. The top ofthe pipe 17 is connected with a block 19, set at the base of water-reservoir 23, and a screw valverod 20 enters the said block and the periphery of which is in communication with the passage of pipe 17, and it is formed with a taper end which closes against corresponding depression in block.. The valve-rod has a hand-rod 21 connected with it, whereby it is operated, and a footpiece 22 at the base of same,which projects beneath the block 19 and forms a radial limitation-stop. The reservoir 23 is designed to fit closely against thel side of the lamp. The top of the reservoir has an opening 24, through which it is supplied with water, said opening being provided with a screw-cap 25. The base of-the reservoir -23 is provided with a tongue 26, which is designed to enter the safety-strapconnection 27, which forms part of the ordinary lamp. The top of the reservoir, at each side, has a ring 28 secured to it, and a chain 29 is connected at one end with one of the said rings, the other end being provided with a hook 30 for attachment to the opposite ring. The chain will encircle the top of lamp-body and (with the tongue 26) hold the receptacle 23 in position. The face of the receptacle 23 is marked (see Fig. 1) to indicate the position of valve when the rod 21 is turned. The cylinder 2 will be provided with a supply of calcium carbid 33, as shown in section in Fig. 2.

The cylindrical hood 5 and cylinder 2 will take the place of the ordinary candle-socket,

and same will enter the socket in the body of lamp and be held there by the means usually provided., In this case a spring-catch 32 is shown.

Assuming the apparatus to be applied to a lamp, as shown on the drawings, the action will be as follows: The water from the recep tacle 23 will fill the pipe to the top of the swanneck 11, and on adjusting the valve by means of the handle 21 the water will drip from the end of the pipe 11 on the wedge head 9 and which will distribute or hn the IOD on the vehicle.

water down along the rod S, so as to come into contact with the calci uni carbid (which is in Contact all around with such rod) in the cylinder 2, so as to generate in an even and regular manner the acetylene gas. The cylindrical hood 5 and the portion of the cylinder 2 above the level of the carbid will form a reservoir for the gas prior to its exit by the burner 7 for combustion. The travel of the vehicle will shake the calcium carbid in to ward the rod S, so that the whole of same will be acted upon by the water in an even manner, and t-he cylnder2 can be easily recharged by withdrawing the cylinder and hood from the lamp-body after having first unscrewed the coupling-cap 16 or removing the flexible portion 18 preparatory to removing the cap 3 for the insertion of the carbid. The wire gauze 3l will form a base for the carbid during filling and valso act during the working of the lamp as a safety-screen against any downward travel of flame vthat might otherwise get at the calcium'carbid portion of the lamp.

I do not confine myself to the particular form of valve herein described,as another suit able form of valve might be employed to allow the adjustable downward escape of the water from the receptacle 23.

Ixeverting to the coupling-nut 16 and the flexible hose 1S, I would have it understood that such adjustable connections have been specially provided so that the pipe connection may be uncoupled and moved aside when the socket 34 of the lamp is put into its holder It' preferred, the flexible portion 1S might be dispensed with; but if this be done and the pipes 17 and 12 be in the form of an unbroken tube it will be necessary to remove both the coupling-nut 16 and the watertank from their positions when lifting the lamp-socket 34 into or from its position in the holder of the vehicle. By preference I remove one end of the flexible portion 18 from either the tube 17 or 12 and then withdraw the cylinder 2 and hood 5 by loosening the.

spring-catch at 32 in the usual manner.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In combination, a cylinder to contain calcium carbid, a lamp-body, a cylindrical hood attached to said lamp-body and fitting over said cylinder and carrying at its top an acetylenegas burner, said cylinderhaving a Vertical rod set within it with wedge head at top, a

watencontaining receptacle fittingonto lampbody, a pipe from the said receptacle to the cylinder having a swanncck with outlet over the wedge head aforesaid and a valve to control water-outlet from receptacle to pipe substantially as and for the purposes described.
